Worry and anxiety are examples of excessive thinking which injure the harmony of the Spleen. In oriental medicine, the Spleen secures residence to the intellect, or Yi. Pensiveness disrupts the Spleen in its function to absorb nutrients and generate blood, and worry thereby accelerates aging by ultimately weakening blood that carries nutrients required for cellular regeneration.
When the Spleen is healthy, Yi communicates with frequencies of our world with clarity, using the process of thought to direct our actions, integrated with greater Universal flow. Too much sitting or emotional entanglement allows mental process the range to become a source of illness and obfuscation.
